Theo, I have heard the LP12, P9 and Avid. Avid Volvere is one of the best TTs I know of for the money. Its upgraded version, the "Sequel" is eerily close to the Acutus sonically and some even prefer it to the Acutus. Rega P9 is good, it sounds different (transparent, clean, a bit CD like) and is in the same league as LP12 at best so it may not be an upgrade per se. Volvere is definitely in a different league!!
And yes if you like UK style of music making (PRAT, jump, boogie) you will not like the VPI :).
